Quality of Experience in Telemeetings and Videoconferencing: A Comprehensive Survey

Telemeetings such as audiovisual conferences or virtual meetings play an increasingly important role in our professional and private lives. For that reason, system developers and service providers will strive for an optimal experience for the user, while at the same time optimizing technical and financial resources. This leads to the discipline...

Multi-sensor capture and network processing for virtual reality conferencing

Recent developments in key technologies like 5G, Augmented and Virtual Reality (AR/VR) and Tactile Internet result in new possibilities for communication. Particularly, these key digital technologies can enable remote communication and collaboration in remote experiences. In this demo, we work towards 6-degrees of freedom (DoF) photo-realistic...

Business considerations in creating a social TV experience

This paper proposes a framework to assess the business feasibility of TV services creating a social TV experience. This framework should enable designers and business decision makers to assess the business potential of services enhancing social communication such as Social TV, social gaming services and telepresence video conferencing.

On the passage of time: Temporal differences in video-mediated and face-to-face interaction

This paper examines team work over time in video-mediated non-collocated and traditional face-to-face same-room teams. In a longitudinal between-groups design, 22 three-person teams were tested in 4 1-h test sessions at 2-week intervals. A paper-folding task was designed for the experiment that had the potential to induce differences in team...

Effects of long-term use of video-communication technologies on the conversational process

This paper examines the conversational process in video-mediated groups as compared to face-to-face groups. In a longitudinal between-groups design, 22 three-person groups were tested in four one-hour test sessions at two-week intervals. In each session, groups had to select and argue the correct answer out of three alternatives from a total of...

Seeing is believing: Communication performance under isotropic teleconferencing conditions

The visual component of conversational media such as videoconferencing systems communicates important non-verbal information such as facial expressions, gestures, posture and gaze. Unlike the other cues, selective gaze depends critically on the configuration of cameras and monitors. Under isotropic videoconferencing conditions people see each...

Amino acid-catalyzed conversion of citral: Cis-trans isomerization and its conversion into 6-methyl-5-hepten-2-one and acetaldehyde

Under alkaline conditions, amino acids or proteins catalyze the deacetylation of citral, a major aroma component, resulting in methylheptenone and acetaldehyde formation. 3-Hydroxycitronellal is an intermediate in this reaction. Amino acids also catalyze the cis-trans isomerization of the pure isomers of citral, geranial, and neral. Most likely...
